Valori restituiti

Matrice di tipo Process che rappresenta tutte le risorse di processo in esecuzione nel computer locale.

Esempio

Nell'esempio seguente vengono recuperate le informazioni del processo corrente, i processi in esecuzione nel computer locale, tutte le istanze del Blocco note in esecuzione nel computer locale e un processo specifico nel computer locale. Recupera quindi le informazioni per gli stessi processi in un computer remoto.

Commenti

Utilizzare questo metodo per creare una matrice di nuovi Process componenti e associarli a tutte le risorse di processo nel computer locale. Le risorse di processo devono esistere già nel computer locale, perché GetProcesses non crea risorse di sistema, ma associa le risorse ai componenti generati dall'applicazione Process . Poiché il sistema operativo stesso esegue processi in background, questa matrice non è mai vuota.

Se non si desidera recuperare tutti i processi in esecuzione nel computer, è possibile limitare il numero utilizzando il GetProcessById metodo o GetProcessesByName . GetProcessById crea un Process componente associato al processo identificato nel sistema dall'identificatore del processo passato al metodo . GetProcessesByName crea una matrice di componenti le cui risorse di Process processo associate condividono il file eseguibile passato al metodo .

Commenti

Utilizzare questo metodo per creare una matrice di nuovi Process componenti e associarli a tutte le risorse di processo nel computer specificato (in genere remoto). Le risorse di processo devono esistere già nel computer locale, perché GetProcesses non crea risorse di sistema, ma associa le risorse ai componenti generati dall'applicazione Process . Poiché il sistema operativo stesso esegue processi in background, questa matrice non è mai vuota.

Se non si desidera recuperare tutti i processi in esecuzione nel computer, è possibile limitare il numero utilizzando il GetProcessById metodo o GetProcessesByName . GetProcessById crea un Process componente associato al processo identificato nel sistema dall'identificatore del processo passato al metodo . GetProcessesByName crea una matrice di componenti le cui risorse di Process processo associate condividono il file eseguibile passato al metodo .

Questo overload del GetProcesses metodo viene in genere usato per recuperare l'elenco delle risorse di processo in esecuzione in un computer remoto in rete, ma è possibile specificare il computer locale passando ".".
